The DeWALT D25134K-QS rotary hammer is a compact 800 W tool designed for drilling, chiselling and light demolition in masonry and concrete. It features a keyless chuck for rapid bit changes and delivers a high impact rate for efficient penetration. With a maximum concrete drill diameter of 2.6 cm and the ability to use core cutters up to 6.5 cm, the tool combines power and manoeuvrability in a 3 kg body finished in DeWALT yellow and black.

Advantages

The 800 W motor provides consistent power for common drilling and chiselling tasks while a high impact rate of 5540 bpm increases drilling speed in tough materials. The keyless chuck enables quick, tool-free bit changes, improving workflow on the job. Its 3 kg weight and compact design offer better control and reduced user fatigue during extended use. The model supports both standard masonry bits and larger core cutters, expanding its range of applications.

How to use

Select an appropriate drill bit or core cutter for the material and hole size, insert it into the keyless chuck and tighten by hand following the tool-specific locking procedure. Secure the workpiece if possible and set the hammer function as required for drilling or chiselling. Start drilling at low speed to establish the hole, then apply steady pressure while allowing the tool to work at its rated impact rate. For chiselling, use controlled short strokes and reposition frequently to avoid overheating the bit. After use, release the chuck, remove the bit, clean the tool and store it in a dry place.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, ear protection and dust mask when working with masonry and concrete. For best results in large-diameter or deep holes, use sharp, correctly sized bits and allow the tool to cool periodically during extended operation. Follow local safety standards and the manufacturer's maintenance guidance for lubrication and inspection of carbon brushes and the chuck mechanism.
